Am I missing

Answer 1

My answer would be, check if the app pool is up and well?

I've seen this error occurring when the app pool has died due to exceptions being thrown that aren't caught.

Consider for example, custom config sections - having an error in there, will cause your app to fail before it's even started. Too many of these in a short space of time will kill the app pool.
